So sorry to disappoint you but there is no such thing as a healthy tan! A tan is visible proof that your skin has been damaged. In my earlier description of the structure of your skin I mentioned cells called melanocytes. These cells produce a dark brown pigment called melanin which gives the skin its natural colour. When skin is exposed to UV rays the melanocytes spring into action by producing more melanin in a bid to absorb the UV and protect the underlying structure. I suppose you could say that melanin is your body’s natural sunscreen but with an SPF of just 2 it really offers only the scarcest of protection. Even if you possess gorgeous skin of colour such as an Afro-Caribbean or Asian skin tone you still need to protect your skin. Yes, darker skin does have increased melanin, but definitely not enough to protect you from the harsh effects of UV rays. The sun may feel good on your skin but UV rays cause the skin to age rapidly - leading to uneven pigmentation, leathery texture and deep wrinkles. Repeated sun exposure can also cause age spots. An age spot is really a solar lento (a tiny bit of pigmentation caused by sun exposure). But the dangers of sun exposure are not just on the surface. Your skin protects your body from destructive outside forces and contains the necessary elements that are essential to the good health of your immune system. The epidermis (outer layer of skin) contains Langerhan Cells which prevent bacteria from attacking your immune system and just a few minutes of UV exposure can damage these cells. The best way to protect yourself is by using an effective sunscreen, of which more later!http://kateloganbeauty.blogspot.com/2009/12/healthy-tan.html​
